We can supply a bounding box to specify the dimensions for the drawing panel defined by

<div id="jxgbox" class="jxgbox" style="width:500px; height:500px;"></div>

The JavaScript code

var board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox:[-5,10,5,-2], axis:true});

sets the vertical and horizontal units and the position of the origin such that the upper left corner of the drawing panel has position (-5,10) and the lower right corner of the drawing panel has position (5,-2).
